Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
MIME-tools doesn't handle empty MIME boundaries correctly. This may |
| 19 |
prevent some virus-scanning programs which use MIME-tools from |
| 20 |
detecting certain viruses. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
MIME-tools is a Perl module containing functions to handle MIME |
| 26 |
attachments. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |
|
| 31 |
------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |
------------------------------------------------------------------- |
| 34 |
1 dev-perl/MIME-tools < 5.415 >= 5.415 |
| 35 |
|
| 36 |
Description |
| 37 |
=========== |
| 38 |
|
| 39 |
MIME-tools doesn't correctly parse attachment boundaries with an empty |
| 40 |
name (boundary=""). |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
An attacker could send a carefully crafted email and evade detection on |
| 46 |
some email virus-scanning programs using MIME-tools for attachment |
| 47 |
decoding. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All MIME-tools users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=dev-perl/MIME-tools-5.415" |
| 61 |
|
| 62 |
